(2) Green area
Indicates the recommended vertical speed range.
Note: ‐ The aircraft can also fly in the grey vertical speed range, without the risk of conflict
(preventive RA).
‐ The color of the vertical speed needle and the digits corresponds to the appropriate
area.
(3) TCAS message
Appears in red when TCAS cannot deliver RA data, or in case of TCAS internal failure.
PFD INDICATIONS
Applicable to:
In case of RA detection, the vertical speed scale becomes rectangular and the PFD presents vertical
orders on the vertical speed scale. The vertical speed scale background is normally grey, but may be
partially replaced by green and/or red areas.
